Titan Fighting 18 takes place at Memorial Hall in Kansas City, Kan., and Friday’s main card airs live on HDNet.

“We were extremely disappointed when the management for Drew and Rory informed us of the news,” Titan CEO Joe Kelly stated. “However, this is the fight business, and having promoted fights since the age of 24, I’ve dealt with a lot of hurdles in promoting shows. While losing Drew and Rory from the show hurts, we took the news in stride. I am very excited that the fans in attendance at Memorial Hall and those watching live on HDNet are going to see two future stars in this sport step up on short notice and test themselves.”

Jake (a three-time Division I national wrestling champion and four-time All-American) and Jared (a 2010 Division national runner-up and three-time All-American) both competed for Oklahoma State University’s powerhouse wrestling team. Both brothers picked up wins at this past weekend’s Caged Cowboys event in Oklahoma.

Jake now has won four straight and five of his past six since a surprising release from the UFC 2009. He hopes a win over Ott, who suffered a decision loss to Strikeforce/WWE vet Bobby Lashley at Titan Fighting 17, could get him back in the UFC.

Jared, who recently moved to 2-0 with a submission win over John Malbrough, now meets Grinlinton, who fights for the first time in 15 months.

As the UFC 189 tour made its last stop in Dublin, featherweight champ Jose Aldo was met with a torrent of abuse from the Irish fans. It might have been unpleasant, but it might also have been just what he needed.
